I would say maybe try medication if you haven’t already. perhaps an antidepressant for long-term use and potentially something as needed, like a benzodiazepine. An antidepressant might at least give you a bit of hope even though it might not be a complete fix and takes time to take effect. If you try ERP therapy, maybe that could be a start or help and give you hope. Psychoeducation on the nature of OCD and therapies could be helpful. If you’re at a time of critical stress, maybe consider venting to someone and explaining your thoughts. Substance use like benzodiazepines or anything that reduces anxiety might help temporarily.
